The assumption of 6 km does not hold in this instance, and almost nowhere in Iceland. (Sidewalks / pavement is a very different issue. In Iceland and in Norway people may cycle on sidewalks, but should be very, very considerate towards pedestrians.) Not many paths here in Iceland are ever crowded, and then only 30 days a year or so. <br>The roads can be the wrong mix of crowded and fast traffic. Even when paths are crowded, most people except the ones that cycle really fast, will refrain from cycling on roads with speeds over 30. Of course there are exceptions. But those people / those setting out to cycle in that style / modus will probably find their way regardless. The routing is more needed by the timid ones, I think. Perhaps there could be two cycling profiles : A. Young/old/timid/leisurely B. experienced/fast I know bicycle infrastructure planners should take at least two brackets / main styles into account. <br clear="none"></div><div dir="ltr" id="yiv6094751243yui_3_16_0_1_1431575769869_184285">Other routing offers have used "safer" / "safest" ( Ridethecity I think) which gives one the impression there is something inherently dangerous in cycling. <br clear="none"></div><div dir="ltr" id="yiv6094751243yui_3_16_0_1_1431575769869_184283"><br clear="none"></div><div dir="ltr" id="yiv6094751243yui_3_16_0_1_1431575769869_184166">But if I wanted to tag the shared path to indicate a higher speed, say 12 or 20 km/h, how would I do that ? bicycle=designated ?

Hello,<br clear="none">
<br clear="none">
This is because the way <a rel="nofollow" shape="rect" class="yiv6094751243moz-txt-link-freetext" id="yiv6094751243yui_3_16_0_1_1431575769869_183712" target="_blank" href="https://www.openstreetmap.org/way/329593444">https://www.openstreetmap.org/way/329593444</a>
is tagged as footway with bicycles=yes. Here we assume 6km/h. The
preference is not changed, as it is not part of a cycle relation.
Such ways could be crowded with pedestrians and dogs, therefore I
believe the 6km/h are ok considering the values for other way types.
The cyclist is just allowed here, but mainly the way is made for
pedestrians. Graphhopper currently does not take the set width tag,
which is set to 3.0 meters in your example, into account. The
choosen scondary has a speed limit of 50km/h (which is not too fast
for my feeling) and therefore we assume 18km/h without changing the
preference down. As it is not much longer, graphhopper chooses it.
The secondary is not tagged with lanes, but even if there would be
multiple lanes there, graphhopper currently does not evaluate such
information.<br clear="none">
<br clear="none">
Please note that graphhopper would set the preference of the
secondary down if the maxspeed on the secondary was greater than 80.
This probobly should be better changed to "greater or equal" 80km or
even 70 km/h.<br clear="none">
@Peter: Can you change the line
